Vacuum Tube - 6L6, Electro-Harmonix
Superior power Beam tetrode with large plate dimensions and improved grid structure for increased power handling capabilities. Excellent tone and performance compared to most other 6L6 or KT66 types.
- Modeled after the vintage RCA 6L6GC "blackplate"
- Mica spacers with metal springs eliminate tube rattle and microphonics
- 5881/KT66 equivalent
Matched versions of this tube use Apex Matching
RoHS Compliant

Great tubes and a great value!
Very good tubes! Great price!
Bought these to give my 50+year RCA's a rest. This red plate thing must be normal, the same in other amps every time I've tried them. Hmm, may not be long rest....
